In this work, a controllable hydrothermal synthesis of two-dimensional (2D) and three-dimensional (3D) dendritic aluminum phosphate crystals was implemented from a recipe containing alumina, phosphate, nitric acid and triethylamine (TEA) with or without the addition of cetyltrimethylammonium bromide (CTAB). The 2D den…
This paper briefly introduces the water transfer printing craft's basic concepts and characteristics, water transfer printing technology classification, material that water transfer printing technology uses , water transfer printing process of applications and the analysis of water transfer printing technology applica…
Hardfacing weld techniques apply mainly to improve the service life of engineering components either by rebuilding or fabricating a composite layer, which will protect the components from wear, erosion, and corrosion. However, hardfaced deposits are susceptible to cracks compared to the base metal due to thermal cycle…
Using first-principles electronic structure method, we have shown that at experimental lattice constant disordered phases of Mn2NiSn are favorable than the ordered structure. Total moments of the disordered phases are comparable to the experimental value. The large variation of moments at one of the Mn atoms stabilizi…

Grain growth, the most fundamental mechanism forming the internal structure in metallic materials, is affected by not only grain boundary (GB) energy but also other driving forces such as internal stress fields of defects. In order to determine the explicit distinctions between the simulated evolutions and the real me…
Potassium Dihydrogen Phosphate crystals are one of the most popular crystals used for Non-linear Optical applications. Most of the amino acids also exhibit NLO properties. The effect of doping of one of the amino acids, L-tryptophan in KDP crystals has been investigated. Pure and L-tryptophan doped KDP crystals were g…
Potassium sodium niobate (K1/2Na1/2NbO3) powder was synthesized successfully by the combustion synthesis. The raw materials of KNO3, NaNO3 and Nb2O5 were used with glycine as fuel. The thermal behaviour of the precursor was determined using thermo gravimetric analysis (TGA) and derivative thermo gravimetric (DTG) anal…
We consider the problem of distributing the stress-strain state (SSS) characteristics in the body arbitrarily loaded on the outer surface and weakened by a physical cut with a thickness of δ0. It is assumed that δ0 parameter is the smallest possible size permitting the use of the hypothesis of continuity. The continua…
A twin-screw extruder was used to carry out the ring opening graft polymerization of L-lactide onto cellulose through reactive extrusion process. Ionic liquid (1-butyl-3-methylimidazolium chloride) [Bmim]Cl and Sn(oct)2 were used as solvent and catalyst, respectively. FTIR, TGA and XRD were used to investigate the str…
Positive ion electrospray ionization mass spectrometry (ESI-MS) was used to characterize complexes formed in aqueous solution between Fe(III), Ga(III), In(III), Ce(III), Eu(III) or Yb(III), and the linear dihydroxamic acid suberodihydroxamic acid (HONHC(O)(CH2)nC(O)NHOH), n = 6; L6H4) at pH 2.5, and at metal (M) to li…
Nanofibers of an acrylonitrile copolymer (acrylonitrile-methacrylate-itaconic acid) are obtained by the electrospinning method from 51.5% NaSCN aqueous solutions at a voltage of 15 kV. The structural characteristics of these nanofibers are investigated. It is shown that, during electrospinning, the interplanar distanc…
A slanted columnar TiO2 sculptured anisotropic thin film is prepared using the glancing angle deposition (GLAD) technique. We extend the inference regarding the optical properties of a uniaxial birefringent film based on theoretical analysis to include the more general case of a multilayer biaxial birefringent thin fi…
Cohesive particles usually form very porous agglomerates. They support loads up to a consolidation pressure, which increases with decreasing particle size. Compaction of nano-powders can therefore be very costly and time consuming. If the particles are electrically conducting, which is the case e.g. for novel nano-str…
We report the transport, magnetic, and thermal properties of La 0.7 Ca 0.24 Sr 0.06 MnO 3 single crystal. It was prepared using floating zone technique used under oxygen pressure of 1 bar with a typical growth rate of 1 mm/hr. The resistivity data shows the metal to insulator transition (M-I) occuring at<mml:math xmln…
In this study, chemical and structural properties of sea snail shell based bioceramic materials (i.e. hydroxyapatite, whitlockite and other phases) are produced by using mechano-chemical (ultrasonic) conversion method. For this purpose, differential thermal and gravimetric analysis (DTA/TG), X-ray diffraction, infra-r…
Electrically conductive adhesives (ECA) are an alternative interconnection method for crystalline silicon solar cells, providing low thermomechanical stress, being lead-free and applicable to new contact structures. The ability to control their curing reaction in a stringing or lamination process is essential for enab…
Fine particles of BiFeO3 were prepared from bismuth nitrate and iron nitrate in KOH solution by hydrothermal reaction. A single phase of BiFeO3 was prepared under hydrothermal condition of K/Bi ≥ 120 and above 180 °C. The TG curves of single phase of BiFeO3 indicated that the products included a small amount of OH gro…
The inhibition of carbon steel corrosion by lignin in two different acid solutions, 1 M HCl and 1 M H2SO4 have been investigated via weight loss methods in varying temperatures of 40, 50 and 60 °C. With the addition of lignin, carbon steel showed less corrosion attack in HCl medium compared to H2SO4. The use of lignin…
Nanorod-like TiO2 (nc-TiO2) and MoO3 (nc-MoO3) films were thermally grown from Ti- and Mo-metallic wafers. Nanohybrid films of N,N’-diphenyl-N,N’-bis(1-naphthyl)(1,1’-biphenyl)-4,4’diamine (NPB)/TiO2 and NPB/MoO3 used as anode/hole transport layer (HTL) heterojunctions in blue organic light emission diodes (OLEDs) wer…
